My son also played T-ball at Kennedy Park and later Little League in Merrionette Park. Very fond memories of watching him at both places. My youngest son enjoyed going to his brother's games solely for the concession stand and playing with the younger siblings of the other players.
I don't mean to speak for either of them, but I know they both enjoyed the Happy Meals from McDonalds, especially when the giveaway had anything to do with Star Wars.

It's interesting that you combined Reds and Kennedy Park. When I was in lower school at Morgan Park Academy, we would always have a picnic at the end of the school year at Kennedy Park. It was always fun and it was the teachers' way of rewarding us for all our hard work. We would always look forward to going to Kennedy Park because it meant the school year was almost over. We would always walk there and on our way we would stop at Reds. I always loved the food at Reds and I was sad when they tore it down.

Does anyone remember Willy's Wayside Wagon? It was a hot dog stand located on 111th Street just east of Central Park in Mount Greenwood. I think it went out of business in the early 1990s.

I remember going there as a child and that they had the best hot dogs around. It was not in a building or anything, it was just a little stand attached to the big building on the south side of the street. All this talk of Reds and Snackville Junction made me think of Willy's Wayside Wagon.
